When Nodes are marked as deprecated in a Companion Specification, it is recommended to create an Object as child of the NamespaceMetadata Object of the Companion Specification and point to that Object using the IsDeprecated ReferenceType. The BrowseName of the Object should indicate the deprecation and the version of the deprecation, e.g., “<SpecName>Version1_02”. An example is the version 1.02 of OPC 40501-1.
